Abstract (en)

[origin: EP3706345A1] The present disclosure provides a method executed by user equipment, including: receiving, by a radio link control "RLC" entity, a service data unit "SDU" from an upper layer. The method further includes: generating, by the RLC entity, a protocol data unit "PDU," the PDU including at least a part of the received SDU, and a sequence number of the PDU being set according to a send state variable. The method further includes: updating, by the RLC entity, the send state variable. Furthermore, the present disclosure further provides corresponding user equipment.
